Species List: La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast 15-01-2015

9 species sighted at La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast.

Terry and Julie on this 107min dive, 28 degree water temp (very balmy), max depth 6.4m, viz 0.2m to 1m.

With the forecast once again being unfavourable for a boat excursion, we opted for a dip in the river. The 0.5m change in tide meant that there was not much current running which resulted in the silt being suspended in the water column. As the tide neared slack water, the visibility worsened and we decided to abort the dive early. The river appears to contain more silt at present and the count number was down. This is possibly just a result of everything being covered in silt. Hopefully the upcoming larger tides will clean it up a bit.
